SebrozCEBRODZ, or "CB" workshop, is a Swiss brand of personalized modified watches co-founded in 2020 by a group of watchmakers and watch collectors with similar creative ideas. It was originally known for its versatile complex watches modified with PATEK PHILIPPE. In the field of watch modification, it is famous for "magic sound three questions". It is good at injecting carving, hollowing out, jewelry inlaying and other techniques into the watch without affecting the original structure, and transform it into a three-tone chronograph that can knock out the "three-tone melody". In 2025, the racing deconstruction (Racing Deconstruction) series will be officially launched worldwide.
